I had the same error, and I solved it by checking the first two items in the screenshot. You can open it by opening system settings ====> software & updates =====> updates tab. After closing the window, type 'sudo apt-get update' in the terminal.

But looking for the held packages returns nothing. Hence, an obvious contradiction. This problem is important because this message obscures the real reasons behind the failure of the often used 'apt-get install' command. The message produced is absolutely not helpful for understanding of what is actually wrong. --- console log showing a problem --- $ sudo apt-get install libqt4-dev [sudo] password for xxx: Reading package lists...
